FAQ

Q: Can I make this casserole ahead of time?
Yes! You can assemble the casserole up to a day in advance, store it in the fridge, and bake when ready.

Q: Can I use uncooked pasta instead?
No, the pasta should be pre-cooked to ensure the casserole bakes evenly and doesn’t dry out.

Q: What can I use instead of Ritz crackers?
Breadcrumbs, crushed cornflakes, or even panko are great substitutes for the crunchy topping.
